Centennial dynamics of floodplain wetland in the largest freshwater lake in China: Implications on floodplain lake restoration

Journal of Environmental Management
Long-term mapping of floodplain wetland dynamics is fundamental for wetland protection and restoration, but it is restricted to decadal scales using satellite observations owing to scarcity of spatial data over long-term scales. The present study concentrates on the centennial dynamics of floodplain wetland in Poyang Lake, the largest freshwater lake ...

Regulation and stability in fish assemblages of neotropical floodplain lakes

Oecologia, 1994
Neotropical floodplain lakes provide an excellent opportunity to examine the regulation and stability of fish assemblages. At low water, when lakes are separated, fish are concentrated in the lakes and are presumably subject to strong interspecific interactions that can shape assemblage structure. At high water, when the lakes and river channels become

The Role of Microorganisms in a Planktonic Food Web of a Floodplain Lake

Microbial Ecology, 2014
Food webs include complex ecological interactions that define the flow of matter and energy, and are fundamental in understanding the functioning of an ecosystem. Temporal variations in the densities of communities belonging to the planktonic food web (i.e., microbial: bacteria, flagellate, and ciliate; and grazing: zooplankton and phytoplankton) were ...

Hydrodynamic and water quality modeling of a large floodplain lake (Poyang Lake) in China

Environmental Science and Pollution Research, 2018
Floodplain lakes are valuable to humans because of their various functions and are characterized by dramatic hydrological condition variations. In this study, a two-dimensional coupled hydrodynamic and water quality model was applied in a large floodplain lake (i.e., Poyang Lake), to investigate spatial and temporal water quality variations.

Ecohydrological control of macrophytes in floodplain lakes

Ecohydrology & Hydrobiology, 2006
Floodplain lakes are one of the most essential habitats for aquatic macrophytes in the modern cultural landscape. Their maintenance and support calls for ecohydrological strategies, as river development, enhanced flood control and other stakeholder interests may have negative impact on the present oxbow ecosystems.

Modelling Nutrient Fluxes in Floodplain Lakes

1997
Only a few years ago Mitsch and Fennessy (1991) stated that modelling nutrient exchanges in wetlands was “now” developing. However, their statement applies to temperate wetlands rather than tropical floodplain lakes, for which still very few modelling studies exist.

Fast response of lake plankton and nutrients to river inundations on floodplain lakes

River Research and Applications, 2008
AbstractKey variables in ecosystems tend to operate on widely different time‐scales. These time‐scales become relevant when a disturbance rocks the ecosystem. Here we try to explain the fast dynamics of plankton and nutrients in the water column of floodplain lakes after disturbances (inundations).

Methane turnover in exposed sediments of an Amazon floodplain lake

Biogeochemistry, 2000
In the Amazon floodplain large areas of unvegetatedlake sediments are exposed to air during low water. Imeasured methane fluxes from exposed sediments of anAmazonian floodplain lake and assessed the regulatingfactors. Methane emission decreased from values between 10 and 40 μmol CH4 mminus 2 hminus 1to zero when the sediments were exposed to air ...

Nitrogen Turnover in Drying Sediments of an Amazon Floodplain Lake

Microbial Ecology, 2005
In the Amazon floodplain large areas are subject to annual cycles of drying and rewetting. The turnover of nitrogen in the periodically drying sediments is an important regulator of floodplain fertility. In the present study the transition of a lake sediment from flooded to dry conditions was studied with respect to microbial nitrogen turnover.
